Warning: Cannot modify header information

When I submit an image this is the error that shows up.

Warning: Cannot modify header information - headers already sent by (output started at /var/www/vhosts/mydomain.com/httpdocs/template/header.tpl.php:6) in /var/www/vhosts/mydomain.com/httpdocs/suggest.php on line 140

Code (markup):

Although this error is showing, when I check to see if it was submitted in the backend of my site, it has. So submitting an image works but have know idea how to fix that error above.

Any help appreciated, thanks.

 

Place at the very beginning of your site the first piece of code to run, this must be the very first line!

ob_start();

PHP:

That will be your problem fixed

check suggest.php, you might have a string echoed or html displayed above line 140.

maybe you can post suggest.php here? so i can tell you which part exactly caused the error..

 

I usually get this when I try to change header information after I have echoed something in php.

 

Thanks, this worked and thanks to everyone else who also posted.
